When it comes to event decor that’s vibrant, versatile, and long-lasting, Mylar balloons are a go-to choice for party planners and DIY decorators alike. Whether you’re preparing for a birthday, wedding, baby shower, or corporate event, understanding how to inflate and deflate Mylar balloons properly can save you time, money, and frustration. In this guide, we’ll cover everything you need to know about handling Mylar balloons — from inflation techniques to safe deflation and storage.
What Are Mylar Balloons?
Mylar balloons also known as foil balloons—are made from a durable nylon material coated with a thin layer of metallic polyester film. This gives them their shiny, eye-catching appearance and makes them more airtight and long-lasting than latex balloons.
Key Features:
- Reflective, metallic surface
- Holds helium or air for days (even weeks)
- Available in various shapes, sizes, and themes
- Reusable if handled correctly
How to Inflate Mylar Balloons
Inflating Mylar balloons correctly ensures they float well and don’t burst prematurely. There are two primary inflation options: helium (for floating) and air (for hanging or standing balloons).
1. Helium Inflation
- Why use it: Helium makes Mylar balloons float, which is ideal for ceilings, bouquets, and centerpieces.
- How to inflate:
- Insert the helium tank nozzle into the valve of the balloon.
- Hold the balloon gently and fill slowly.
- Stop inflating once the balloon is firm, but not overfilled (overinflation may cause seams to split).
Pro Tip: Use a weight to anchor helium-filled Mylar balloons, especially outdoors.
2. Air Inflation
- Why use it: Air-filled Mylar balloons are best for garlands, walls, or attaching to sticks.
- How to inflate:
- Use a balloon pump or a straw.
- Insert into the valve, blow or pump slowly.
- Seal the valve by pinching it closed — no tying is necessary!
How to Avoid Overinflation
Mylar balloons don’t stretch like latex balloons, which means overfilling can result in seam rupture or wrinkles. Here’s how to avoid this common mistake:
- Stop inflating when the balloon is firm but not bulging.
- Look for visible creases disappearing—this signals full inflation.
- Don’t expose the balloon to heat after inflation, as gas expansion can cause it to pop.
How Long Do Mylar Balloons Stay Inflated?
- Helium-filled Mylar balloons can float for 3–7 days, sometimes even longer indoors.
- Air-filled Mylar balloons can stay inflated for weeks, making them great for long-term displays.
Factors that affect longevity include:
- Temperature changes
- Exposure to direct sunlight
- Quality of the balloon
- Seal integrity
How to Deflate Mylar Balloons Safely
If you want to reuse your Mylar balloons or dispose of them safely, deflating them properly is crucial.
Steps to Deflate:
- Insert a drinking straw or balloon stick into the balloon’s valve (the same opening used for inflation).
- Push it gently until you hear the air start to escape.
- Slowly press down on the balloon to release the air.
- Once flat, fold and store in a cool, dry place.
Tip: Avoid sharp objects when deflating; they can damage the reusable valve.
Reusing and Recycling Mylar Balloons
Mylar balloons are reusable, making them an eco-friendlier option when handled with care.
Tips for Reuse:
- Store them flat in zip-lock bags.
- Avoid folding along creases with printing or graphics.
- Re-inflate using the same methods—just check for leaks.
Though not biodegradable, Mylar balloons can often be recycled in programs that accept #7 plastics. Always check with your local recycling facility.
